Q:Why do cheap cars like stamping parts instead of casting parts?: We usually say that the stamping is usually refers to the cold stamping parts, for example, a piece of iron, wants to turn it into a fast food dish, it must design a set of mold, mold is working face plate shape, the pressure plate mold, it becomes you want the dishes, this is the cold stamping die stamping is the direct use of metal materials.Automobile stamping parts are mainly classified according to process, and can be divided into two major parts: separation process and forming process.

Q:What reason is the bronze statue choking fire?: The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,

Q:What kind of flaw detector is better for casting parts?: If you want to detect internal defects, you can use ultrasonic flaw detector, ray flaw detector can also, but the ray of the safety protection level is too high, not recommended priorityMacro Xu flaw detector answered, such as the magnetic particle inspection machine has the demand can contact us, Baidu "macro Xu flaw detection""

Q:In the design of casting steps and precautions, for casting design, we have what experience?.: (3) to prevent generating white grey cast iron, in addition to taking measures from the process, must make the wall thickness is not too thin (some sources indicate that the corner wall thickness above 15mm, metal type casting must be in the corner, for Aluminum Alloy, magnesium alloy casting casting casting Create fillet should not be less than 3-4m, for casting round cast iron, copper alloy mould casting can see table 1.1-32 selection; (5) because of the metal and the core without let, for the convenience of the casting is taken out and the draw out type, slope casting casting should be suitably large than sand casting metal casting. General 30%-50%, it should be pointed out that in addition to the height of the slope of casting size and alloy type, wall, is also related to the casting surface position, where the cooling and contraction and metal surface of casting surface can be designed from the tendency of small inclination, while casting shrinkage tend to be pressed on the surface of metal castings the type should be given greater inclination, all kinds of metal type alloy casting casting casting.

Q:What are the casting parts processing engineering?: According to the classification of process methods, sand casting and special casting.

Q:Why should pig iron be used in casting?: Cast iron is generally called pig iron, but casting is not merely iron casting.For example, injection molding, die casting, and so on, in fact, cast iron, cast steel, cast aluminum, plastic and so on, can be used in the form of casting processing molding

Q:Casting parts have poor surface finish. What sand is used to make them?: Now resin sand, coated sand and other processes are also very good surface.

Q:What are the causes of pitting on the surface of a precision casting?: There is a bump on the mold. Or casting cooling fast.

Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?: Proofing? In the casting industry is not called proofing, proofing is generally used in the printing industry, that is, according to the customer's drawings or samples, to do a first piece, to provide customers with the inspection process to meet their requirements;In the foundry industry, providing prototypes is sometimes difficult:1, customers if the provision of mold, it would be best, at this time, sample costs are very low, and almost the same as your regular products;2, the customer does not provide the mold, but in business relationships, your factory and not very sure must take this one, it requires your leadership decision-making, is free or low cost, or by a strict process offer (of course sample);3, not all of the casting process to provide samples are difficult, like lost foam can directly make a white NC prototype, and then assembled pouring, this is her unique advantages, first cost less than the opening process and so on;If you don't understand, you can continue to question me

Q:Which master knows how the casting tolerances for malleable iron, gray iron and ductile iron should be chosen? Hurry up, thank youCan you provide a tolerance scale for castings, please?: Our country has a national standard for casting tolerance levels. This national standard applies to you in malleable iron, grey cast iron, and ductile iron.
